I tried the latest version (on master branch) of Builder with winpython 3.6.1 and wxpython 4.0.0b1. The Builder window looked ok, but I counldn’t run experiment by pressing “Run Experiment” button. No error message was shown.
I read app/builder/builder.py and guessed flags passed to wx.Execute() were imcompatible with wxphtyon 4, but I’m not sure. How is the state of progress on migration to wxpython 4? Is there anyone who can run Builder experiment on Python 3 and wxpython 4?
